I use my Dell Laptop with Outlook for mail/calendar. Windows 7 is on the laptop. I do not have to sign in to get access when I boot up or to get into Outlook. I bought a Surface 2 and I want to transfer (or sync) my Outlook from my laptop onto my Surface. The apps for calendar and email aren't necessary as Outlook is on the desktop of the Surface and I'm fine with that. But I can't seem to sync my calendar from the PC to the Surface. Do I need to have Windows 8 on the PC in order to sync to surface?
